Are there any AVRs on the market that have an inbuilt sub amp to power a passive subwoofer ?

Almost all AVRs have a sub pre out which needs to go into a separate sub amp, the sub amps tend to be very expansive, but i wondered if there way an AVR with an integrated sub amp ?

I need a separate sub amp as i want to use an in ceiling subwoofer which is passive as opposed to the standard active floor standing subwoofers.

Most companies don't build their AVRs to meet the specs- why would they add a power amp that needs to develop more power than the rest of the channels, combined?

If the AVR has a sub out, just use an amp- you'll have much more flexibility and control over its output, too. You can use almost any power amp- I have used the Behringer A500 and it worked fine. I have also used amplifiers from Skywalker, AudioSource and others with similar success. Don't overthink the importance of an amplifier- if it has the ability to drive the speaker(s) without puking, use it. If it has some kind of DSP to add limiting and compression and/or crossover, even better.

I have never seen AVR with built-in amp for the sub.
Honestly though, if you find some off beat AVR that does, you're opening yourself up to a slew of other issues.

If you have a budget for a decent ceiling sub, find few bills for a good amp.

In some cases, unused AVR channels could be used for this. For example; the AVR is 7.1 and you are only using 5.1 channels. In this case you might be able to patch a channel to use the subwoofer line level output.

In my experience these extra amplifiers are not very robust and I would not be comfortable using them for driving a subwoofer. I'd much rather use an external amplifier.

Integra DSX-3.

But not enough power.

For previously mentioned reasons, you need to pony up for the subwoofer amp.
There is no truth anymore. Only assertions. The internet world has no interest in truth, only vindication for preconceived assumptions.
